Abstract
A display panel includes a substrate including a plurality of pixel regions having sub-pixel regions and a reflective region surrounding the sub-pixel regions, light emitting structures in the pixel regions, the light emitting structures being on the substrate, an encapsulation substrate over the light emitting structures, a reflective member on a lower surface of the encapsulation substrate, the reflective member having openings, each of the openings being located at a corresponding one of the sub-pixel regions, and a light blocking member on an upper surface of the encapsulation substrate, the light blocking member partially blocking a light of a first wavelength.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A display panel, comprising:
a substrate including a plurality of pixel regions having sub-pixel regions and a reflective region surrounding the sub-pixel regions;
light emitting structures in the sub-pixel regions, the light emitting structures being on the substrate;
an encapsulation substrate over the light emitting structures;
a reflective member on a lower surface of the encapsulation substrate, the reflective member being located at the reflective region and having openings, each of the openings being located at a corresponding one of the sub-pixel regions; and
a light blocking member on an upper surface of the encapsulation substrate, the light blocking member comprising:
first portions located in the sub-pixel regions, each of the first portions blocking light of a second wavelength range; and
a second portion located at the reflective region and blocking light of a predetermined wavelength range from among light of a first wavelength range such that the second portion has a first color, a lowermost wavelength of the first wavelength range being greater than an uppermost wavelength of the second wavelength range.
2. The display panel of claim 1 , wherein the light blocking member blocks ultraviolet rays and blocks a portion of visible light.
3. The display panel of claim 1 ,
wherein the second wavelength range is in a wavelength range of ultraviolet rays,
wherein the first wavelength range is in a wavelength range of visible light,
wherein each of the first portions of the light blocking member blocks ultraviolet rays, and
wherein the second portion of the light blocking member blocks ultraviolet rays and a portion of visible light.
4. The display panel of claim 3 , wherein the first portions each comprise a material that blocks ultraviolet rays, and
wherein the second portion comprises at least one selected from a material, a pigment, or a dye that block ultraviolet rays.
5. The display panel of claim 3 , wherein each of the first portions is transparent.
6. The display panel of claim 1 , wherein the second wavelength range is in a wavelength range of ultraviolet rays,
wherein the first wavelength range is in a wavelength range of visible light,
wherein the first and second portions of the light blocking member block ultraviolet rays and a portion of visible light, and
wherein the first and second portions have the first color.
7. The display panel of claim 6 , wherein the first and second portions include at least one selected from a material, a pigment, or a dye that block ultraviolet rays.
8. The display panel of claim 1 , wherein each of the light emitting structures comprises:
at least one semiconductor element on the substrate;
a lower electrode on the semiconductor element, the lower electrode electrically connected to the semiconductor element;
a light emitting layer on the lower electrode; and
an upper electrode on the light emitting layer.
9. A display panel comprising:
a substrate including a plurality of pixel regions having sub-pixel regions and a reflective region surrounding the sub-pixel regions;
light emitting structures in the sub-pixel regions, the light emitting structures being on the substrate;
an encapsulation substrate over the light emitting structures;
a reflective member on a lower surface of the encapsulation substrate, the reflective member including first openings, wherein each first opening is located at a corresponding one of the sub-pixel regions;
a transparent member between the encapsulation substrate and the reflective member, the transparent member having a second opening that overlaps with the first opening; and
a light blocking member on an upper surface of the encapsulation substrate, the light blocking member blocking ultraviolet rays,
wherein the light blocking member is transparent, and
wherein the transparent member has a first color.
10. The display panel of claim 9 , wherein the first opening and the second opening have the same size.
11. An organic light emitting display device, comprising:
a display panel comprising:
a substrate including a plurality of pixel regions having sub-pixel regions and a reflective region surrounding the sub-pixel regions;
light emitting structures in the sub-pixel regions, the light emitting structures being on the substrate;
an encapsulation substrate over the light emitting structures;
a reflective member on a lower surface of the encapsulation substrate, the reflective member being located at the reflective region and having openings, each of the openings being located at a corresponding one of the sub-pixel regions;
a body surrounding the display panel; and
a light blocking member on the display panel and the body, wherein the light blocking member protects the display panel, and wherein the light blocking member comprises:
first portions located in the sub-pixel regions, each of the first portions blocking light in a wavelength range of ultraviolet rays such that each of the first portions of the light blocking member blocks ultraviolet rays; and
a second portion located at the reflective region and blocking light of a predetermined wavelength range from among light of a first wavelength range in a wavelength range of visible light such that the second portion has a first color, the second portion of the light blocking member blocking ultraviolet rays and a portion of visible light.
12. The organic light emitting display device of claim 11 , wherein the light blocking member comprises at least one selected from a material, a pigment, or a dye that block ultraviolet rays.
